Abstract:
AIM To research the chemical constituents from dried roots of Uncaria yunanensis Hsia.C.C. METHODS Modern chromatography was used to isolate chemical components. Their structure were identified by spectral analysis. RESULTS Seven compounds were isolated and identified as 3β,6β,19α-trihydroxyurs-12-en-28 oic acid (I), 23-nor-24-esomethylene-3β,6β-19α-trihydroxyurs-12-en-28 oic acid (II), 3-oxo-6β,19α-dihydroxyurs-12-en-28 oic acid (III), oleanic acid (IV), 5,7,3′,4′-tetrahydroxy-flavan-3-ol (V), β-yohimbine (VI) and diangoutengjian I (VII). CONCLUSION All of the above compounds were isolated for the first time from the root of this plant. Among them, compound VII is a new one.
